Track Specific Classes

For performance reasons, only the top 20 application classes in the heap are tracked automatically.

Use the Configure Custom Classes to Track option on the Object Instance Tracking subtab to specify instances of specific classes to track. Note that the classes you configure here are tracked only if their instance count is among the top 1000 instance counts in the JVM.

To track instances of custom classes:

  1. On the Object Instance Tracking tab, click Configure Custom Classes to Track.
  2. On the Instrumentation page that displays, click the tier you want to customize.
  3. In the Object Instance Tracking section for the tier, click Add.
  4. Enter the fully-qualified class name of the class to track and click Save.
The class you added is now tracked during object instance tracking sessions.
